P-100 SPF Primer

SKU: P100-SPF PRIMER-55

Our P-100 SPF Primer (often called Night-Seal) is used to seal your spray foam projects overnight. For those projects when you don't have time to apply a top-coat or haven't completed all foam passes, use our SPF Primer to protect your foam from UV degradation until you can complete them.

Available in: Black color and 5 and 55-gallon containers. 

Application: Spray-applying is recommended.

Details

P-100 SPF Primer is a plasticizer-free, single component, water-based, acrylic primer developed to prime aged asphalt, SPF, metal, wood, and concrete surfaces, improving the adhesion and overall yield over sprayed polyurethane foam. P-100 is designed with specialized polymers and wetting agents that maximize adhesion. P-100 also has the unique ability to “breathe”, providing a completely watertight membrane while allowing trapped moisture to escape.

Storage and Shelf Life: P-100 has a recommended shelf life of 12 months from the date of manufacture when stored in unopened containers between 50°F and 100°F. Refer to product packaging for date of manufacture.

Application
